Fontbakery Technical Report

If you think a check is flawed or have an idea for a check, please file an issue at https://github.com/fonttools/fontbakery/issues and remember to include a pointer to the repo and branch you're checking.

DEPRECATION WARNING

By late-December 2024, FontBakery version 0.13.0 introduced a new naming scheme for the check-IDs.

Fontbakery detected usage of old IDs and performed an automatic backwards-compatibility translation for you.
This automatic translation will be deprecated in the next major release.

Please start using the new check-IDs as documented at /Lib/fontbakery/legacy_checkids.py

The following legacy check-IDs were detected:
- com.google.fonts/check/outline_semi_vertical
- com.google.fonts/check/outline_short_segments
- com.google.fonts/check/fontdata_namecheck
- com.google.fonts/check/outline_colinear_vectors
- com.google.fonts/check/ttx_roundtrip
- com.google.fonts/check/outline_alignment_miss
- com.google.fonts/check/version_bump
- com.google.fonts/check/outline_jaggy_segments

Ensure the font supports case swapping for all its glyphs.

Check ID: <FontBakeryCheck:case_mapping>
🔥 BaskervvilleSC-Regular.ttf
  • 🔥 FAIL

    The following glyphs lack their case-swapping counterparts:

    Glyph present in the font Missing case-swapping counterpart

Check if each glyph has the recommended amount of contours.

Check ID: <FontBakeryCheck:contour_count>
⚠️ BaskervvilleSC-Regular.ttf
  • ⚠️ WARN

    This check inspects the glyph outlines and detects the total number of contours in each of them. The expected values are infered from the typical ammounts of contours observed in a large collection of reference font families. The divergences listed below may simply indicate a significantly different design on some of your glyphs. On the other hand, some of these may flag actual bugs in the font such as glyphs mapped to an incorrect codepoint. Please consider reviewing the design and codepoint assignment of these to make sure they are correct.

    The following glyphs do not have the recommended number of contours:

    - Glyph name: Eth	Contours detected: 3	Expected: 2
